Recently, in Japanese convenience stores, kiosk terminals have started providing customers with travel and ticket sales services with operators by phone. However, these systems have many problems: customers often make mistakes in operating kiosk systems and in calling experts, and children often play with the terminal and make unnecessary calls to experts. We propose an information kiosk system where service providers can control the telecommunication channels by the cooperation between agents and experts. This system uses three kinds of agents: a kiosk agent, a manager agent and an expert agent. Our proposed system allows experts to effectively and politely deal with customers in a timely manner. We designed the structure of a prototype system based on this proposal, and we clarified problems for the implementation of this system.

XML has became a very important emerging standard for E-commerce because of its flexibility and universality. Many software designers are actively developing new systems to handle information in XML formats. We propose a generic architecture for processing XML. We have designed an XML processing system using the latest technologies, such as XML, XSLT (XML Stylesheet Language Transformation), HTTP and Java servlets. Our design is very generic, flexible, scalable, extensible, and also suitable for distributed network environments. A main application of the architecture and the system is to support data exchange in E-commerce systems.

This paper presents our hybrid architectural model for distributed data mining (DDM), which is tailored to meet the needs of e-businesses in which application service providers sell DDM services to e-commerce users and systems. The hybrid architecture integrates the client-server and the mobile agent technologies. This model focuses on the optimisation and costing issues of DDM, which are particularly relevant in the context of billing users for data mining services.

Most e-services are typically delivered point-to-point; however, the e-service environment creates the opportunity for providing value-added, integrated services, which are delivered by composing existing e-services, possibly offered by different companies. This paper presents eFlow, a model and system that provides a flexible, configurable and open approach to service composition. In fact, eFlow has an adaptive and dynamic process model that allows processes to transparently adapt to changes in the environment, to customize service execution according to the customers' needs, and to cope with exceptional situations. In addition, the model and the system are configurable, so that applications running on devices with limited storage space and computing power can download a version of eFlow that only includes needed features and that has a smaller footprint with respect to the complete version.

DWINS is a dynamically configurable Web-based information system we built for inventory management. It is flexible, secure and active. The database structure can be adjusted any time, even after the system has been configured and starts running. All existing functions are applicable on all new database objects once they are created. Furthermore, the functions of the system are not fixed and key operations can easily be extended and configured. High-level security is implemented by checking permission before any operation is actually carried out. Flexible fine-grain level access control is achieved with the combination of access level, group control and user access list mechanisms. By providing an alert manager, the system can actively notify the users when important events occur. Thus the system is no longer simply waiting for user commands passively but plays a more active and important role.

This paper presents a new Web-based technique for visualizing dynamically large hierarchies, tree or category structures in 3D worlds. The technique uses CGI-scripting, SQL queries and applet-based production systems to visualize in an efficient and versatile manner general category structures that are stored in relational databases. First, appropriate SQL queries extract the hierarchical category or tree structure from the database. Then, the minimal information is transmitted over the net to the user's applet that generates a production system according to an optional visualization model. The interactive applet builds the corresponding 3D world and visualizes the category structure. As a test-bed for our Web-based visualization technique we use a commercial e-commerce framework and extended it with the corresponding features. We illustrate our technique by visualizing the complete mall structure according to different visualization models, such as axial trees, cone trees and enclosure models, for instance.

We propose domain name service (DNS) server extensions to support global replicated services. The DNS server collects routing metrics from routers for cached replicated servers. Upon receiving a DNS request from a host in its domain, the DNS automatically returns the IP address of a server available from an IP address pool that has the best routing metrics preferred by the host. Possible extensions to routers are proposed to support routing information collection. These router extensions work independently of the specific routing protocol used by the routers. The route metric collection mechanism is also independent of DNS extensions and may be used for other purposes. Our approach makes it much easier for content providers to support global replicated services flexibly and transparently. The network latency perceived by users is reduced substantially because of network proximity. Simulation results show that our approach is much better than DNS round robin. Moreover, the overhead introduced by our extension is negligible.

Negotiation between buyer and supplier parties is an important part of commerce activities. Complex conditions are exchanged during a negotiation. It is important to realize a database of such conditions and provide querying facilities in an advanced electronic marketplace. We introduce the notion of dynamic constraints to model such complex negotiation conditions, and propose a new query language, called the dynamic constraint algebra. The algebra can classify and match dynamic constraints based on properties. We also show algorithms for processing dynamic constraint algebra queries.

This paper describes two architectures for building pay-per-run software systems: the download-once approach and the dynamic-download approach. These are systems that allow the user to pay for each execution of an application, instead of buying a more expensive user license. This is a new model for software distribution in which developers charge small fees for each execution in order to increase their user market. We detail each component of the architectures and compare both approaches.

Efficient means of electronic interaction are an essential requirement for the integration of different companies' business processes along the value chain. Until recently, this interaction relied on expensive, complex and inflexible solutions, mostly based on EDI or some proprietary means. The high set-up costs and time associated with this type of infrastructure prohibits the dynamic forging of business partnerships, which is of utmost importance to the services industry. The CrossFlow architecture supports the dynamic establishment and enactment of a business relationship between two organisations, based on a contract that specifies this relationship. This is achieved by creating an electronic market where advertising and searching for compatible business partners takes place. This is further enhanced by automating the set-up of the contract enactment and supervision infrastructure, and by connecting them together to allow the business processes of the partners to cross their organisational boundaries.
